Updated: 2013 preseason QB snap counts

NFL teams have played their most important snaps of the 2013 exhibition season now that every team has played at least three games.

This becomes a good time to check out how many snaps each projected starting quarterback has played. The players listed in the chart below entered preseason as the quarterbacks I considered most likely to start season openers. We might have to make adjustments in some cases.

Teams have different priorities based on a range of factors. This snapshot does provide some context.

A few notes regarding the NFC West info:

Arizona Cardinals:Carson Palmer appeared sharper in the preseason opener than he did subsequently. Pass protection was one problem against San Diego on Saturday night. Palmer still got 37 snaps, his highest total of the preseason. But with the team losing key players Rob Housler and Jonathan Cooper to injuries, snap counts for Palmer were not a leading storyline.

St. Louis Rams:Sam Bradford has played 25 snaps in each of the last two preseason games. He is averaging 10.2 yards per pass attempt in the preseason and has a 114.1 NFL passer rating to this point (he finished the 2012 preseason with five touchdown passes, no picks and a 116.3 rating). The team's most recent preseason game, at Denver, provided Bradford a good opportunity to connect with Jared Cook, the tight end St. Louis lured away from Tennessee in free agency with $19 million in guarantees. Cook caught four passes for 50 yards and a touchdown.

Seattle Seahawks:Russell Wilson took three sacks and threw two interceptions while playing 38 snaps against Green Bay in the most recent preseason game. The Packers, meanwhile, pulled Aaron Rodgers after 10 snaps. Seahawks coach Pete Carroll said the Packers came after Seattle with scheme-related wrinkles an offense would address in the regular season, but not preseason.
